2 Claims.

This invention relates -to cameras .and more particularly to a foldablecamera, the machine portion of which is made in one piece and which canbe readily assembled into a workable pinhole'icamera. This invention isan improvement on the camera shown in my Aprior Patent No. 2,559,214,issued July 3, 1951, and the front portion thereof is very similar.lThis improvement deals `mainly with'the rear portionof the camera andwith the spool lm holding means and operating structure.

Further and more specific objects, features and advantages will moreclearly appear from a consideration of the specification hereinafter setforth when taken in connection with the accompanying drawings whichillustrate a further form of my camera.

Briefly, the invention comprises a blank of suitable material such ascardboard which can be die-cut in suitable form and which includes aplurality of sections, flaps and tabs joined by creased lines which whenfolded together and assembled form an actual operable, simple andefficient camera with a pinhole opening and an oscillatable shutter. Theback of the camera is pivoted so that it may be opened to insert aregular roll of film and can be locked shut by the same means whichholds the operating knob that winds the film.

In the accompanying drawings- Fig. l is a perspective view of a cameraem bodying my invention.

Fig. 2 is a cross-sectional view showing the interior of the camera.

Fig. 3 is a sectional view taken on the line 3--3 of Fig. 4.

Fig. 4 is a sectional view taken on the line 4-4 of Fig. 3.

Fig, 5 is a detailed view of the operating key.

Fig. 6 is a detailed view of the end of a conventional reel which thekey shown in Fig. 5 engages.

Fig. 7 is a plan view of the blank from which the camera is made.

Fig. 8 is a detailed view of the lock slide.

Fig. 9 is a detailed view of the shutter.

Referring more particularly to the drawings, the blank Ill is made up ofa plurality of sections. Segments II, I2, I3, I4 and I5 when folded intoplace form the top, bottom and the two sides of the camera. Segments IB,Il, I8, I9, and 2i form the complete side of the front of the camera.Segments 22, 23, 24, 25, 26 and 21 fold into the camera to form thesimple supports for the spools of a roll of film which rest on thevertical pieces 22 `and 25. Segmenten,

29, 30, 3|, 32, 33 and-34 form the back 0f the' tape members ylil andthe shutter v36 inserted in place as well as the keyl lock slide 35. Thesegments 30, -3I and 33 are provided with .slots 4i. Segments Il and I9are yapertured at 42 vand segments I8 and `2li 'at 43 so that when thefront is assembled the light -may .pass .through 'the pinhole entry.

The key 3l is provided with a knob portion 45, a recessed portion 46 anda roll engaging portion 4l. This roll engaging portion will engage theend A of the film roll. The key slide 35 is provided with an invertedkeyhole 48 with its wider portion at the bottom through which the shankof the key 3l can pass. When the keyslide is in an upward position thekey may be removed and the camera openedy but when the slide is pusheddownwardly the narrower portion of the keyhole opening engages therecessed portion v46 of the key 31, thus locking it in place. Themovement of the slide is limited by a rivet 49 mounted in the slot 4| inthe segment 30. The shutter 36 is pivoted by means of a pin through theopening 50 and is positioned behind the panel 20 to cover and uncoverthe opening 43.

When it is desired to use the camera the back is opened and a roll offilm is inserted with the spindle engaged in the cut-out portions 52 ofthe segment 22. The end of the lm is engaged in the conventional spindlewhich is positioned with one end supported by a similar shoulder 52 andthe other end extending through the opening 53 in the segment I2 whichwhen the camera is closed will register with the opening 54 in thesegment 30. The key is then inserted with its inner end engaging the endof the spool and the lock-slide brought down to lock the camera shut. Atab 55 in the member 32 is bent upwardly and apertured to form a sightand a covered opening 56 is provided to register the lm and to show themovement of the nlm in use. A small diaphragm having a pinhole 51 isinserted between two of the front members and behind the shutter. Oncethe back has been closed and the knob turned to expose the lm, thecamera is in position to take a picture.

Cameras of this type, of course, are time cameras and the shutter mustbe opened for a few seconds time, depen-ding upon the light and othercircumstances involved.

The segment I6 has two depending legs 60 and 6I which fold in under theface of the camera to limit the motion of the shutter 36. In otherwords, the shutter 36 operates between the legs 60 and 6| to avoidexcess motion. Since the shutter has a cut-out portion defining a leg 62it is only necessary for it to move the width of the said leg.

While I have shown a specific form of my invene tion, certainmodifications and changes may be made without departing from its spirit,and I do not wish to be limited to the specific form shown.

I claim:

l. A camera formed of one piece of material foldable upon itself to formbottom, top and side walls and a back section, a portion of saidmaterial defining lm holding means within the body of said camera, anopening in the side wall of said camera aligned with one of said nlmholding means, an opening in the back section aligned with said rstmentioned opening, a sliding member having a key-hole opening sopositioned that when moved in one direction the larger portion of saidkey-hole opening coincides with the iirst two mentioned openings, a filmoperating member having a recessed portion extending through all threeopenings and locked in place when the sliding member is moved so thatthe smaller portion of said key-hole opening is in a line with the firsttwo mentioned openings and engaging said recessed portion of the filmoperating member so that the side wall and the back section are lockedin place.

2. A camera formed of one piece of foldable material deiining bottom,top and side walls, a back section hinged thereto to close the rear ofsaid camera and to cover the major portion of the inside of said sideWalls, means on one of the side portions of said back section to supporta film spool, an opening in one of said side walls and a correspondingopening in the other side wall of said back section, a side membermovably mounted in said side section having a key-hole opening therein,a film operating member comprising a knob and a key engaging theopposite end of said spool, said film operating member extending throughsaid openings in the side walls and back section and through saidkey-hole slot, said iilm operating member having a recessed portion tobe engaged by said key-hole slot when said slot member is moveddownwardly to hold said lm operating member in position and to lock saidback section in place. f
